finafloxacin + amoxicillin

Finafloxacin + amoxicillin is a combination of two antibiotics. Finafloxacin is a fluoroquinolone antibiotic that acts by inhibiting bacterial type II topoisomerase enzymes, specifically DNA gyrase and topoisomerase IV, which are essential for bacterial DNA replication, transcription, repair, and recombination[4][6]. It has demonstrated activity against a broad spectrum of bacteria including multi-drug resistant strains and is approved as an otic suspension (Xtoro) for the treatment of acute otitis externa ("swimmer's ear")[1][2][4][5]. Amoxicillin is a beta-lactam antibiotic in the penicillin class that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins; it is widely used to treat various infections such as pneumonia and bronchitis[3]. The combination would theoretically provide broad-spectrum antibacterial coverage through dual mechanisms—disruption of DNA processes (by finafloxacin) and inhibition of cell wall synthesis (by amoxicillin).
